[SR-Users] Dmq usage

[José Seabra]

The 7 dmq messages that the node receives seems that are re-transmissions.
I think that you must call the dmq_handle_message() function within your
REDIS route in order to stop re-transmissions, but i'm not sure, make a
test please.

Regarding to that ERROR msg that you sent, it seems that your servers have
network problems, because  if the DMQ server doesn't receives the 200OK to
the DMQ Options the nodes will be removed from the list.
